The present invention is directed to 'improvements in direction signals for motor vehicles.

The primary object of the invention is to provide a device of this character so constructed that indicia upon the rear end of the vehicle will be illuminated to indicate to following traflic the intended course about to be traveled by the car, the illumination of the indicia being controlled by the steering gear of the vehicle. With the above and other objects in view, the invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Fi re 1 is a side elevation of an automobile s owing the friction plates thereon.

Figure 2 1s a front view of the switch con taining casing, with the front cover removed. Figure 3 is a sectional view on the line 3-3 of Figure 2.

1 Figure 4 is a view of the signal casing.

Re erring to the drawings, 1 desi atesa ctaising which includes a vertical ringo 2 of e vehicle. 1 This casing has an intermediate partition wall 4'mounted therein and is formed from suitable insulating material, the bottom 5 of said casing being likewise formed from insulating material and is provided with a lon- 'tudinal slot 6, the purpose of which will be fi ter explained. Carried by the partition 4 are outer binding posts 7 and an intermediate binding post 8, the former being connected with the resilient arcuate contacts leading therefrom and connected with the bulbs, not shown, in the signal box 11 which is mounted upon the rear end of the vehicle, said box having glass panels therein bearing indicia, such as the representation of hands, or, if desired, the words Right and Left may be used in lieu of the hands, as'may suit the fancy of the manufacturer.

Connected to the post 8 is a bracket 13 and u to which is connected the upper end of the ted to be bolted to one of the side sills them bemg "conducting wlres 10-10 of the switch arm 14 the clasp 1 switch arm 14, said arm being movable in the 'slot 6 of the bottom 5.

To the lower end of the arm is connected at block 15 of suitable insulatin material, the rear end of which is connects to the casin 1 by a coil spring 16. A clasp 17 is enga with the steering rod arm 18 and to which is attached the forward end of a wire 19, the rear end thereof being secured to the forward end of the block 15. Leading from the post so 8 to the. ignition circuit of the vehicle is a conductor 20. v

It will be obvious that when the vehicle is traveling in a straight course that the switch arml i will be positioned between the lower ll terminals of the contact strips 9-9, at which time the signal will not be illuminated. However, as soon as the car is turned to the right or left, the switch arm 14 will be moved accordingly through the medium of the arm 18 and wire 19 and will contact with one of the strips 9-9, thus closing the circuit and illum-' inating the signal to indicate the direction about to be traveled.

The tension of the s ring 16 is such that 16 when the vehicle is ma 'ng a left hand turn the arm 14 will be drawn rearwardly for contact with a strip 9. The wire 19 will move forwardly when the vehicle is making a right hand turn, thus contacting with the so ot er strip. o

I It will, of course, be understood that. the signal will be placed in operation only after the ignition switch has been turned on.

Thus, when the car is parked and the ignition Ii switch is turned 05,- can be turned at any nating the signal.

Should it be desired to cha e the throw may be adjusted vertically upon the arm 18. Having thus described the invention I claim: 1'. v

Circuit cIosin'gmeans for a motor vehicle signal com e front wheels thereof angle without illumitudinall otted wall,a partition adjacent the wall opposite the slotted wall, an arm pivoted at one end to'the center of the partition and projecting through the slotted wall, resilient contact strips at the sides of the 1" rising a casing having a longi- 5 arm connected at one end to the partition and curved concentric with the pivot of the arm and having their terminals spaced apart to clear the arm, bindinglposts forming connecting means between t e pivoted arm, contact strips and partition, an element pivoted centrally to the outer end of the arm, a contractile spring connecting one end of the pivoted element with the casing, and an operating element connected to the opposite end of the said pivoted element.

In testimon whereof I afiix m signature. HAROL M. HEGYESS [1,. 5.]
